_common had rotted into a junk drawer. Trim it to what actually
justifies a shared leaf module and rename for legibility:
* REPO_DIR: deleted (dead — nothing imported it).
* read_tty_line: dropped the pointless re-export; cleanup/start/init
now import it straight from bot_bottle.util.
* USER_CWD: deleted. It captured os.getcwd() at import time, but
nothing chdirs and no test patched it, so it was equivalent to a
live os.getcwd() — inlined at the six call sites.
* PROG: kept, now the sole member. It's still a leaf (both the
dispatcher and the commands it imports need it) so it can't move
into __init__ without a circular import.
_common.py -> constants.py. Full unit suite green (2243); CLI dispatch
verified.

"""`backend` CLI command — generic host setup/status across backends.
|
|
|
|
`./cli.py backend setup [--backend=NAME]` provisions (or points at how
|
|
to provision) the chosen backend's one-time host prerequisites.
|
|
`./cli.py backend status [--backend=NAME]` reports readiness.
|
|
`./cli.py backend teardown [--backend=NAME]` undoes setup (uninstall).
|
|
|
|
All dispatch to the backend's `setup()` / `status()` / `teardown()`
|
|
classmethods, so there are no backend-specific commands — swapping
|
|
backends is just a different `--backend` (or `$BOT_BOTTLE_BACKEND`, or
|
|
the host default).
